Model 53i IP Phone User Guide  27

Setting a "BLF List Key"
(For use with the BroadSoft Broadworks Rel 13 or higher platform only)

The BLF\List feature on the IP phones is specifically designed to support 
the BroadSoft Broadworks Rel 13 Busy Lamp Field feature.
This feature allows the IP phone to subscribe to a list of monitored users 
defined through the BroadWorks web portal. 

Note: Your system administrator must have BLF List enabled on the BroadWorks 

Server. Contact your system administrator for more information.

In addition to monitoring the idle and busy state, the BLF\List feature also 
supports the ringing state. On the 53i phone, the LED lights next to each 
BLF programmable key illuminate steady to indicate the monitored line is 
off-hook or unregistered. The LED goes off when the is idle.  When the 
monitored extension is ringing, the LED flashes.

Note: The Broadworks BLF feature is not the same as the Broadworks Shared Call 

Appearance (SCA) feature and does not permit call control over the moni-
tored extension.

Example
A receptionist has a 53i running Broadsoft firmware that subscribes to a list 

of extensions from the BroadWorks Application Server. On the 53i running 

Broadsoft firmware, the programmable key LEDs illuminate either 

flashing, solid, or turn off depending on the state of those extensions.

Note: You can also use a BLF/List configured key to dial out.

1. Click on Operation->Programmable Keys.

2. Select a "Key 1" through "Key 6".
3. In the "Hard Key" field, select "BLF\List" (BroadSoft BroadWorks).

Note: The "Label" and "Value" field are not required. The BroadWorks BLF List 

name is configured in the "BLF List URI" field instead.

4. In the "Line" field, select a line number that is actively registered to the 

appropriate SIP proxy you are using.
